The Moxa IMC-21-M-SC is a compact and reliable industrial Ethernet media converter.
It seamlessly bridges 10/100BaseT(X) copper Ethernet connections to 100BaseFX multi-mode fiber networks.
This device is ideal for connecting PLCs, HMIs, sensors, and other Ethernet-based devices to fiber infrastructure.

Reliable Ethernet-to-Fiber Connectivity

In industrial environments, network stability is critical.
The Moxa IMC-21-M-SC delivers consistent performance, even in harsh operating conditions.
Its rugged plastic housing ensures durability in demanding locations such as factories, utilities, and transportation systems.

With its multi-mode SC fiber connector, this converter supports transmission distances of up to 2 km.
This makes it perfect for short to medium-range industrial applications without the cost of long-range solutions.

Enhanced Network Reliability with LFPT

The Moxa IMC-21-M-SC includes Link Fault Pass-Through (LFPT) technology.
LFPT detects link failures instantly, ensuring quick response to network issues.
This feature improves uptime and prevents undetected network failures in mission-critical environments.

Flexible Configuration Options

For easy setup, the device provides DIP switch configuration.
You can select full or half-duplex mode, 10/100 Mbps speed, or auto-negotiation.
This flexibility helps adapt the converter to different industrial network requirements.

Space-Saving Design and Easy Installation

Measuring only 30 x 115 x 70 mm, the IMC-21-M-SC fits into space-limited environments.
It supports DIN-rail mounting, making it ideal for control cabinets or electrical panels.
The design ensures quick and clean installation in any industrial networking setup.

Wide Operating Temperature Range

This industrial fiber converter operates from -10°C to 60°C.
It maintains consistent performance in cold storage facilities, hot factory floors, and outdoor enclosures.
Such a wide range makes it suitable for varied industrial environments.

Energy Efficiency and Long-Term Reliability

The Moxa IMC-21-M-SC consumes very little power—only 250 mA at 12-48 VDC.
Low power usage reduces operational costs and supports energy efficiency goals.

Its MTBF of 335,000 hours ensures long-term stability.
With fewer failures, you reduce downtime and maintenance costs.
